Specification of Letters Patent:

' Patented July 16, 1907.

l Application filed April 11,1905. Serial No. 254,946.

To all 'u'ho/rt it may cannrm:

Be it known th;at we, EDYARU IIAMLuANN and ()rm'nnns II; Moons, citizens of the United States, and residents of New York city, in the county oi New York and State oi New York, have invented a new and useful Improvement in Water-Closets, oi which the iollowing is a specification.

This invention appertains to certain novel and useiul improvements in water closets and consists oi certain novel parts and combinations oi part; particularly pointed out in the claims concluding this specification.

.\\hile we have in the present instance illustrated and described one iorm oi our invention which we at pres ent prcier, we wish it to be understood that we do not 5 limit ourselves to all the precise details oi construction thereof as modifications amlchanges may be made in details without departing iijinn the spirit oi our invention and without exceeding the scope oi the concluding claims. In the accompanying drawings like characters oi reference indicate like arts in all the views, and

Figure lisa pcrspect \e view of a bowl involving our invention; Fig. 2 is a tiip plan view of the same; Figs. 3 and i are views partly in elevation and partly in set. tion-showing the interior oi the bowl, and especially illustrating the construction oi the rim. Fig. 5 shows a modified form oi bowl in which we dispense with the elevations or ledges at the front and rear. Fig. (3 is a view partly in elevation and partly in vertical longitudinal section oi a closet such as shown in Fig. 5

' Rcierring now to the accompanying drawings in detail, the numeral 5 indicates the water closet bowl constructed of a suitable material such as porcelain, and having a flushingrim 6 extending entirely around the sairie, such rim beingconnected with a suitable source of water supply by means of the elbow 7 and pipe 7" 'at the rear of the bowl. The rim (5 is constructed in hollow or tubular form, so that a channel extends entirely and completely around through the rim, the portions of the channel 9 at the sides oi the bowl being relatively larger or deeper than those parts 10, and 11, of the channel which pass respectively at the iront and rear of the bowl. This construction is clearly shown in Figs. 3 and 4. At the front of the bowl the sides d5 of the rim merge in an elevated ledge 12, which is ex- "tended and recessed at 13, in such manner as to iorm a shield at the iront oi the bowl. Similarly at the rear of the bowl the sides of the rim merge in the ledge 14, which is rcarwardly concaved to iorm a recess 15. .The effect oi forming a bowl in this manner is to give a larger suriace within the interior oi the bowl, for it will be noted that in ordinary bowls the rim extends entirely around the bowl, and is of substantially the same depth at the front and rear ends. In such a case the rear of the rim is liable to become soiled and inasmuch as it lies above the. point. oi discharge oi the flushing medium into the bowl, such portion oi the rim must be cleaned manually. but with our cutaway or recessed rim there is littlryiliability oi the rim being soiled, inasmuch as the recess extends upwardly approximately to or even slightlyabovc the level oi the seat and any substance instead oi'collecting on the rim will lodge in the rec irom whence it is readily removable by means of the Hush. In order to accomplish the thorough flushing oi the main portion of the bowl as well as the recessed parts just described, we provide the rim with a row of perforations 16, formed in the under side oi the rim and communicating with the channel 8 at a point close to the vertical wall of the hopper bowl, so that as the water passes into the channel and out through the poriorations 16, it will flow directly down over the interior surface of the entire bowl and not spray or shoot outward toward the center oi the bowl, as is usually the case. It will further be noted that the row of perforations follow the direction of the under side oi the rim, that is to say, extend up into the recessed portions oi the front and rear ledges or shields heretoiore described, so that any substance lodged in such recessed portions will be washed therefrom and the recess thoroughly cleaned.

The upper, outer suriaee oi the. sides oi the rim or edge oi the bowl are approximately in the. same horizontal plane, and in Figs. 1, 2, f5 and 4 of the drawings the'bowl is provided with the elevated shield or ledge at the front and rear, as has been described. In this construction at one side oi the rear ledge is hinged at 17 a sectional seat member 18 oi wood, or other suitable material, and adapted to coniorm in contour to the sid oi the bowl, such member having a small rubber projection 19) adapted to rest on the upper edge oi the rim, the iree end oi such scat member terminating at a point adjacent to the side of the front shield l2. Similarly, a sectional seat member 20 is hinged at 21 at the rear oi the bowl and has its [rec cud terminating at the opposite side edge of the front shield. This mei nber is also provided with a buiier or projection 23 secured to the under side thereof and adapted to bear against the top oi the rim when the seat is in the position shown in Figs. 1, 2 and 3, the scat sections, when closed, being approximately in the same horizontal plane. By employing such sectional scat certain sanitary advantages are obtained inasmuch as it is our desire to dispense with as much woodwork in the construction oi the invention as is possible.

In Fig. 6, we have shown a slightly modilied form of construction, in this case, dispensing with the raised ir'ont and rear shields or ledges, but we still retain the concaved or recessed portion. at the rear oi the bowl, no

v dent to our improved apparatus will be appreciated.

It will be apparent that the bowl embodies many advantages from a sanitary standpoint inasmuch as the entire inner surface thereof may be flushed and the 1 5'Iilushing water issuing from the channel-of the rim will,.

owing to the location of the apertures, flow down close along the sides of the bowl portion instead of shooting outward toward thecenter oi the bowl. The advantages incident to the recessed portion of the bowl other than those referred to, will also be apparent and it is unnecessary to describe the same in dotail. It is further to he noted that the rear portion of the rim is of relatively less depth than the sides, and the channel portion at such rear and front is correspondingly reduced relative to the size of the side channels, so that an in creased space at the front and rear of the bowl is at? tained. I p

in our co-pending application for water closet apparatus filed-December 7, 1903, Serial No. 184,210, we have shown a construction of apparatus embracing amongst other features, a closet bowl having a recessed elevated portion at the front thereof, a recessed elevated portion at the rear thereof, and means for flushing the bowl and the recessed portions. Furthermore, in

.in such application, Serial No. 184,210, we have embodied claims generic to the subjects-matter of said application, and the present application Serial No. 254,946. Therefore, in the present application we do not intend to claim any subjects-matter generic to both applications, but make such claims in ouizcarli er ap- .0 T plrcation Serial ho. $4,210, and wish to be so understood. But 'the present inventie i1 is in the nature ofan improvement over the invention set forth in an earlier application Serial No. 184,210, and the claims.

herein are intended to be so directed.

Having thus described our invention, what we claim and desire to secure by Letters Patent is:

l. A water closet lmving tne channeled rim of varying i depth formed with an elevated recess at the front of the howl. a second elevated recess at the rear" of such bowl, and means for introducing a flushing agent into said rim and from thence into the recesses and the main portion of the howl to cleanse the some.

2. A water closet howl having a rim of relatlvelydess depth at its rear than at the sides, and having perform tions in such rear portion whereby the rear interior of the closet may he flushed. I

3. A water closet huvinga howl provided with a rim of I relatively less depth at the rear than at its sides andhaving an elevated recessed'shield or ledge at thefro'nt of the howl, and an elevated recessed shield orledge 'a't the rear thereof, and means for flushing the recesses.

4. A water closet lng entirely around thesame'. such rimheing of relatively less depth ut the rear than at the front thereof, and havins; perforations formed therein close tod'he wail of the howl for permitting the howl to he flushed.

d. A water closet howl provided with a continuous flushlng rim having anelevntcd recessed portion at the rear, of the howl and an elevated recessed portion at the front of the howlfhoth such elevated portions helng flushed from the flushing rim, and a seat member formed of two sections spaced apart at the front and rear to accommodate the recessed elevated portions of the howl at the front and rear.

(i. The combination with 11' water closet bowl having a flush rim extending entirely around the same, the front and rem portions of said rim being elevated shove the rest of the howl. of u sent cut away at the front and rear to accommodate the elevated portions of the bowl at the front and rear, such sent lying suhstunti'a'liy flush with the elevated portions of the howl.

in tcsih'nony whereof we have signed our names to this specification in the presence of two-snhscrihing witnesses.
